Gum!

But, before my co-op….Bethany finished her last peer reviewed guitar exercise and last writing assignment. It was the first time that we recorded the melody and chords and put them together – it sounds better in the beginning, then the chords get off a bit from the melody, but not bad for the first time doing that. Hannah and Grace were at separate sleepovers and I got a call right before the co-op that Grace threw up. I wasn’t sure if it was something she ate, the smoke or what. She seemed fine at the library, though she was tired and spent the whole time asleep in the closet (it was cool and dark in there.)

OK, so for the lab everyone brought some gum. You could tell that most of us don’t normally give our kids gum (Hannah had 15 pieces of Trident gum in her mouth before the class even started!)

The first thing we did was look at the gum and notice its shape – was it a cube, rectangular prism, sphere? Then everyone weighed one piece of gum (later we would weigh it after chewing.) We commenced chewing the gum and talked about whether it was undergoing a physical or chemical change.

Everyone thought physical after I explained both of them. We talked about what was happening to the gum, why was it getting soft – saliva or temperature or both? Everyone came up and got a cup of ice cold water to drop their gum in, the gum changed back into a solid – so temperature has a lot to do with gum changing from solid to semi-solid. We blew bubbles and measured the diameter (to later record the circumference of the bubbles) and talked about how the gum was now full of gas. The sugar-free gum blew from 2-4 cm diameter and the gum with sugar was ranging from 4-10 cm in diameter (we probably would have recorded bigger bubbles if we had tried again at the end of the co-op.) The kids came up and weighed their gum again, amazing results! I sent home a reminder that we had not talked about the fact that the weight and density of the gum had changed even though the mass remained the same.

Then we got to do the fun part that no one every lets you do with gum – take it out of your mouth and stretch it as far as you could.

The sugar-free gum was ranging from 12-24 inches and the sugared gum all the way up to 4 feet! (They were measuring one piece of gum, except for Hannah, she had about 5 pieces in her mouth.)

We noted the color change too, the Orbitz gum went from purple to gray, the other gums pretty much stayed the same color.

Lastly, I asked the kids to come up with their own imaginary gum.

They had to tell me what color, flavor and shape the gum was going to be, create a package for the gum, price it, and they could create a jingle for it too. We had Cora’s mystery space gum (only $1.01!), her jingle was, ‘C-O-R-A-S gum, Cora’s gum!’ with a little tune that went up and down and she actually used some chewed gum to attach her wrapper design to the package design paper (well, you don’t have any tape she said, touche!)

We had Coconut gum, Peach Paradise gum, Cinnamon toast flavored gum and more.

Alanna made A’s bubbles, this is her package and the wrapper for the pina colada flavored gum.

I liked Andrew’s:

it’s bacon flavored gum (very popular right now), he’s skating on thin ice with a trademark lawyer using Bubba Hubba as the gum name, also his jungle was, ‘Brown bacon, yum!’ which sounded just like the Red robin jingle, his ingredients are corn syrup and stuff, the gum costs $100 and you only get 1 cm of gum in the container. But hey, if you’re going to dream, dream big! T made a gum that was pineapple flavored with pop rocks in it, I like the packaging – it’s like see through dice.

I did not get pictures of all the work, but they were all great.

That was a fun co-op and here is some more fun stuff about gum:

-During WWII, U.S. military personnel spread the popularity of chewing gum by trading it and giving it as gifts to people in Europe, Africa, Asia and around the world.
-Cinnamon, spearmint and peppermint are among the most popular flavors of chewing gum today.
-Chewing gum while cutting onions can help a person from producing tears.
-The color of the first successful bubble gum was pink because it was the only color the inventor had left. The color “stuck,” and today bubble gum is still predominantly pink.
-The largest bubble ever blown was 23 inches in diameter. The record was set July 19, 1994 by Susan Montgomery Williams of Fresno, CA.
-Blibber-Blubber, a failed attempt at bubble gum, was invented in 1906 but was deemed too sticky to sell.
-The ancient Mayans chewed plain chiclé. That’s a latex sap from the sapodilla tree.
-Swallowed gum won’t clog up your intestines, but it will be with you for a few days. Gum base can’t be digested so it will pass through your system in one piece.
-Singapore has tried to completely forbid gum, with heavy fines of over $6,000 for possession or use without a prescription.
-Studies have shown that chewing gum actually helps people concentrate and may improve long-term and working memory. Chewing gum has also been shown to reduce muscle tension and increase alertness.
-Turkey is the country with the most gum companies; the United States is second.
-Chewing gum burns around 11 calories per hour.
-In 2006 the world-wide chewing gum industry was estimated to be worth $19 billion in sales, or 1.3 million metric tons of gum.
-Chewing gum on an airplane will keep your ears from popping. Chewing gum makes your salivary glands produce 250% more saliva than normally, so you swallow more. This helps balance the pressure in your head.
-In the U.S. alone, the total amount of chewing gum sold in one year would make a stick 3.5 million miles (5.6 million km) long. That’s long enough to reach the moon and back seven times or to circle the earth’s equator 150 times.
-Chewing gum after meals may help prevent heartburn.
-The largest piece of bubble gum ever was the size and weight of 10,000 regular pieces and was presented to baseball player Willie Mays by the Topps Chewing Gum Company in June 1974.
-Back in the 1920’s, prohibition increased gum sales because people needed to mask the alcohol on their breath. When prohibition was enacted, Adam’s Clove gum hit the market with the slogan: “It takes your breath away!”
-Chewing gum was illegal in all of Eastern Europe until Czechoslovakia began manufacturing it in 1957. Poland and East Germany quickly followed suit, but it was not until 1976 that the Soviet Union lifted its ban on gum.
-Humans are the only animals on earth that chew gum. If you give a monkey a piece he will chew it for a couple of minutes, then he will take it out and stick it to his hair.

Make your own gum!

River sampling

My river co-op was today. We met Sabrina at the Platte river at Grant frontier park and did a few things. First, we did some basic water sampling with Ph, nitrates, temperature, phosphates and oxygen.

The Ph was a bit lower than last time, everything else was about the same (except the temp., it was warmer.) We found out that Colorado is one of two states that are headwater states (that means that water flows out of our state and not into it.) The other state is……Hawaii. That makes Colorado unique and it means that our water is important to not only us, but also to the other states and eventually the ocean that our rivers flow into.

We played a game of river tag. Everyone had a card with a water bug on it and 2 people were water stressors. The kids with bug names had to cross the ‘river’ without getting tagged. If they got tagged they had to change their tag (like going from a caddisfly to a midge) showing that the water quality was getting worse. It worked, in the end we had more midges and rat tailed maggots than flies. (Stressors are biological or chemical agents that act on the insects in the water, it could be ash from a fire, phosphates from detergents, etc.)

Finally, we went to the river to do some bug sampling.

The kids took turns gathering things in nets and dumping them in buckets, then we picked out some of the bugs from there and put them in an ice cube tray so they were easier to see. We found snails, leeches, mayflies, caddisflies, stoneflies, worms, and other things in the water. This did not deter the kids from swimming and many of them waded out or plopped in tubes and floated down the river.

We had perfect timing to end the co-op, our ‘isolated thunderstorm’ moved in right at the end and started drizzling us. Grace needs to meet with Ronnie for fishing and send her report from last time to Casey and then we need to spend some time cleaning up the area around her patch of river (and it needs it.) But, we’ll choose a nice hot day, then we can clean and float at the same time.

Hike

But first, school. Bethany had to finish a written test for math, do some peer reviews in Nutrition, take some quizzes in Guitar and do peer reviews in Writing. Grace and Hannah did some reading and spelling. After lunch we went to Waterton canyon for a co-op hike with some friends from our homeschool group.

We didn’t see much wildlife (unless you count the snake that was eating another snake…) but the weather was nice and the views were pretty.

Sometimes you see bighorn sheep and sometimes not, this was a not day. After 2 miles in we stopped and let the kids play in the water.

Grace found a caddisfly after much searching (and its tiny little rock house attached to a flat rock.) Here is a picture of what that looks like, the rock house Grace found was broken and the fly was just roaming around the rock. I would have taken a picture, but it was the same color as the rock, so I don’t think you could have seen it.

Once we rested for a bit, we turned around and hiked back. We saw this family of geese on the way back.

Waterton is a nice easy hike and much better on a day that is cloudy.

Thursday

This morning we did some school, Bethany turned in her guitar assignment (by uploading recordings to Soundcloud) and turned in her Nutrition assignment (dinner – round steak in cream of mushroom soup, garlic spaghetti squash and garlic couscous.)

Grace wrote a post to tell everyone about the WAVES symposium coming up in September (Fabien Cousteau is one of the speakers!) Hannah finished up LOF Edgewood and was reading Nate the Great to me. We went to lunch with Dad (since he was home) at Chipotle and then the girls and I went downtown to The Gathering Place for a tour and to drop off donations.

I had planned for this tour to only be for little kids so that Grace and Hannah could be on this one, Bethany was the only one that was supposed to be at the other tour, so we got twice the information about TGP. We did ask some different questions and got answers about things like: Why is this shelter only for women and children? (Because there are already shelters for men and the environment there tends to be not as safe as a place with only women.) Why is TGP only open during the day? (Because there are many night shelters for people to sleep in, but they have beds covering the floor space and no room to have other things like healthcare, library, play area, and so on.) How many people come to TGP on a daily basis? (About 250-300, more in the summertime.) Is everything free? (Yes, you can see a doctor, work on a computer, take a crafting class, drop your kids off at the daycare, get food, get clothing, find bus routes, make calls on their land lines and more – for free.) Do you have to be homeless to go to TGP? (No, you can be short on food for the month and come get food, they serve the homeless, the poor and those who just need a little help with something during the month.) We dropped off food in the food pantry and books for the kids and adults.

After the tour we dropped some books and puzzles off at Lambuth house (since we were so close) and then got a snack at Littleman’s. I took the girls to Walmart where Hannah spent some of her birthday money on dresses, a nightgown, an itunes card and a wallet. Grace got a new swimsuit and Bethany got new swim shorts. Now we’re all set to swim. James made dinner and we watched some TV, I was tired from…..I don’t know what, but just tired.

CU, recycle, tea and cheese

I’m sure that won’t make any sense to most people. We started our day at the CU natural history museum.

We wandered the exhibits and Hannah read some books to me. They still have the bug exhibit downstairs, but they added curiosity cabinets to the mix and moved the furniture around.

Upstairs they had a (no photography allowed) pottery exhibit and the usual dinosaurs.

We had planned to eat lunch at Waffle brothers, but they are closed for the summer, who closes for the summer (apparently Waffle bros.) So we ended up in a food court eating Nepalese food. Hannah ordered the chicken momos and the lady said the order came with 12, Hannah said ‘great!’ I’m sure the lady didn’t think Hannah could eat 12 momos, but she could have (I stole 3 of them for Grace, her veggie momos were too spicy for her to eat.)

Next we headed to our co-op at the Ecocycle center in Boulder. They have a booming business due to the crunchy nature of most Boulderites. People in Boulder are just different, they are a little bit greener and crunchier than Denverites – which is great for a place that does recycling.

Our guide Dale told us about the facility, it has items in it made from lots of recycled things like: the bathroom stalls and counters are made from detergent bottles, the carpet is made from water bottles, recycled tubing was made into skylights and more.

Trucks bring in all the recycled goods and dump them in a warehouse, then the conveyor belt takes over.

The cardboard is the first to get weeded out. The fluffer machine throws the paper up into the air so the bottles, glasses and plastics can go down through a hole.

The glass goes one way, the paper and plastic another.

On one line people stand at the belt sorting plastics: are they milk jugs? Detergent jugs? Lids? Plastic #3-7?

They were very fast at their job. The plastic and paper gets baled and loaded onto semis that take it to another center.

All glass bottles go to the Coors company to be made into beer bottles. They sort out the colors and trade with wineries to get brown glass for the extra white and green glass they have. We learned that there are things you shouldn’t recycle (TV tray cartons, they have plastic in them; shredded paper, it goes everywhere; wrapping paper, it’s too thin to make paper out of; lids, they get stuck in the paper or get lost on the floor.)

They have a really nice location in Boulder, they made the processing plant on a hill so that water goes down into a wetlands area, there were plenty of birds and animals taking advantage of the habitat. Their job is to recycle as much as possible so that very little goes into a landfill, because once there it sits forever.

After the tour we hopped over to the tea shop to buy some tea (Sleepytime peach, Honey vanilla chai and Peach green tea) and to try some samples. Then we went over to Longmont to the cheese shop. When we pulled into the parking lot we were confused, there was no sign, no door on the warehouse – we thought the worst (no cheese!)

But, I called the store and it turns out they had moved to Main street into a cute old building that has way more room than the old place.

The first floor has the cheese fridge, bistro, bar, restaurant and sundry items for sale (and bread.)

The 2nd floor has a kids area with books, a puppet show and games for sale, a place to hang out and eat or work and an area that shows off the perfume, soaps and lotions for sale (and looked like a made to order photo shoot area.)

So, we took pictures.

I am so glad they moved, we will be stopping in every time we’re near Longmont!

Tales, the park, music and art

Yesterday I had my trickster tales co-op at the MOA art park. I like showing off places that people have never been to. Almost everyone at the co-op had never been to the park at Fiddler’s Green, but now they know what a cool place it is. In the Summer when the Weidenblume sculpture is covered in willow leaves we like to lie in its shade and do school.

The willow is just starting to leaf out and even now it gives a bit of shade. I read Arrow to the Sun, Pig Boy and Jabuti (all by Gerald McDermott.) The first book is a Pueblo Indian tale, not so much trick as a tale of how boy came to earth and how rainbows were made. The second book is a tale from Hawaii, the third is set in the rain forest and is a tale of how the tortoise got a cracked shell.

After the readings we glued colored paper shapes (or just colored) a turtle, some of the kids got very creative with that part, some didn’t do it at all and everyone had some time to play at the park.

After the co-op we went up the street to Westlands park for park day. Annie wasn’t too sure about my new camera, she had just gotten used to the old one, now I’m going to have to win her over with the new one.

The kids played in the brush (yes, they have an entire playground and they choose to play in the gully and trees, I love these kids.)

The parents talked while the kids played, ahh park day. The weatherman was correct and right on time it started to rain and hail in typical Colorado afternoon thunderstorm fashion. It was good to get out and see so many friends, some of which we hadn’t seen in ages.

Today we started school on time (because Daddy was working from home) and everyone got through in record time. Bethany was able to record her guitar playing and upload it to her Coursera guitar course before the deadline (4 hours before, but it was still before the deadline.) We weeded through the library books that needed returning and headed out to the EK meeting at Mcd’s for a late lunch. No one showed up to the meeting, so we ate and I let the kids play while I finished up my May article for ColoradoEdNews. Then we drove by CORE art gallery to see Bethany’s art piece.

It looks so tiny hanging underneath a huge painting, but it’s the biggest piece she’s done (she did another 16X20, but this piece is a bit bigger than that due to the inch of space between the 8X10 canvases.)

It will be there for the rest of May and part of June (wanna buy it? $125 and it’s yours.) We dropped off more books at a different library (and I still have more books that need to be dropped at our library) and then we went home. Grace read Corduroy and some of Aesop’s fables to Hannah (it’s going back tonight) and then they all went out to play.

I love it when a day (or two) comes together.

Science on a sphere and hoodoos

We had a co-op today in the Springs at the Space foundation. We got to see science on a sphere as we learned about plate tectonics, satellites, weather patterns and more.

We watched the current weather roll in from satellites parked around the globe.

We talked about the earth’s crust, here’s what the earth looks like stripped of the oceans.

We talked about convergent, divergent and transformational boundaries.

We watched the Japanese earthquake hit and watched the tsunami roll across the ocean to South America. The DMNS has a sphere too, but what is on it is limited and there isn’t always someone there to explain it. After the sphere show we went into the classroom to do some hands-on activities. First, we talked about the three types of rocks, where you find them, how they form and what they are made of. Our guide was using the torch to heat some sediment (sugar), showing us what would happen to the rocks that end up in magma.

We saw sedimentary rock layers (we could look out the window to see an example of that, Garden of the gods was across the way.) Then our guide mixed some rocks, sediment and water and poured it into a waffle iron to transform with heat and pressure (don’t worry, it was just flour, sugar and water.) We got some clay and started working on pressing plates together, thin and thin plates smash to make mountains.

Thin and thick plates smash and the thin plates go under the thick one; thick and thick plates move kind of side to side like a transform boundary. After this lesson we went into the visitor center to do a scavenger hunt.

We found out that Alan Shepherd was the first American in space in 1961 (at first the kids thought the question was who was the first man to walk on the moon, but it was who was the first American in space.)

We searched through information about rockets, space suits, rovers, landing units and more.

We found out that Russian astronauts ate their food from cans instead of pouches and that they like to eat fish products for breakfast (yum?)

The geology lesson was just what my girls needed (just started earth science) and we are going to be doing hiking and rock-hounding this summer, so rocks and minerals and formations will be on our list of things to learn about, this was a good introduction.

I had been waiting for a nice day and a trip to the Springs so we could hike at the Paint mines. Well, today was the day and the girls were excited to try out some of their new knowledge about rocks.

We arrived at the park, it looks like a pretty normal plains hiking area.

You start on the path (any trail will take you to the same place) and it isn’t long before you start to see hoodoos, spires and a canyon beneath you.

Sometimes the rocks (sandstone, shale, rhyolite, Castle Rock conglomerate, and selenite clay ) look like science fiction movie sets.

The Native Americans in the area used the clay for paints and for pottery, miners later used it for making bricks.

Erosion from wind and weather has made the spires and hoodoos, the valleys and blueberries (something we just learned, blueberries are small round rocks made by water erosion.) We walked up a dry stream bed and took the trail around some of the formations.

There were a few flowers blooming here and there.

We found a ground wasp busily cleaning out his hole.

The girls got lost in a maze of spires while I watched from the top.

We read about the geology of the area and marveled at the fact that we were thousands of years down in a canyon and wondered what it would look like in a few thousand more years.

After the hike we stopped in at Focus on the Family for some ice cream and play time. We made it home by 5:30 and I put spaghetti and meatballs on for dinner. I’m glad we made it to that hike, it’s not a god summer hike (no trees) and we’ve been wanting to go there. We’ll have to go back though, we missed out on the toy museum and huge antique store in town (closed on Mondays, sigh.)

Tuesday

We got a late start to school then left for the cake decorating co-op. I left on time, but forgot the cakes, so we had to turn around and go back home. Thankfully I was only 5 minutes from the house.

We arrived at the co-op and got started with bags of icing and practice sheets.

We used a few different tips to make stars, stripes, circles and a basket weave.

Hannah was working very hard on the practicing part.

Once the kids were happy with how the practice turned out, they frosted their cakes and started adding decorations.

Hannah’s cake looked like the beach, purple and white shells were everywhere.

Grace had a red velvet cake with orange frosting and white and purple stars and purple stripes.

Bethany had a lemon cake with white icing, a blue rose and pink stars.

We took the cakes home and brought one to Grandma’s place (3 cakes to eat – what was I thinking.) We had dinner with Grandma and then took her to the library to watch a play with us.

It was Aesop’s fables with actors from Page to Stage. They told us a little about Aesop and then we heard 5 stories. The fox and the crow, the fox and the grapes, the tortoise and the hare, a wolf in sheep’s clothing and the sun and the wind.

The girls thought the turtle was funny and the wind was cool with his mohawk hair. We checked out some books and showed Grandma the check out system on the computer. It’s come a long way from pulling the card off the book and stamping it.

River sampling and aeronautics

Grace had her second river meet-up today. We met with Sabrina from Riverwatch to assess the river and do some bug sampling. Casey from Cherry creek watershed joined us for a bit as did Mr. Ronnie (a local.)

Grace spent about an hour doing a river assessment and chemical sampling and about 45 minutes doing bug sampling.

Here are some of Grace’s notes:

4/26 9-10:45am Grant Frontier park Platte river
cloudless blue sky
water temp – 53 F
turbidity – 10 JTU
nitrates- 5
O2 – 3
percent of bare earth on banks – 30%
smell – normal (this means normal Platte river smell, it doesn’t stink, it just has a kind of odor that you know is the Platte)
Items: tagged trees for removal, trash in river, bag of trash near bank, one nosy goose
Bugs gathered in sample: leeches, alderflies, mayflies, stoneflies, blood worms, adult mayfly.

After lunch we went to a co-op at the light rail bridge. We made spinners that acted like maple seeds (helicopter seeds), the only problem was the wind kept pushing them back onto the bridge.

So the kids changed locations.

We made parachutes and dropped them off the bridge, hmmm….would a lighter chute work better? Shorter strings?

Lastly we tied a string onto the top of the rail and taped it to the bottom pavement. Then we hooked a straw and balloon onto the string and let them fly up and then go back down.

Grace found out she could blow up her balloon again and again, until it finally popped. It was a nice day, maybe a bit too much wind for what we were trying to do, but still a gorgeous day.

Tomorrow – free light rail train rides, giveaways, prizes, food, art and fun on the new W line!

Castle rock museum

The snow ended last night and the sun came out this morning, so the roads were fine for the museum co-op. The Castle Rock museum is tiny, you can’t see it from the freeway and unless you knew about it, you would never know it was there. (I found out about it from a booth at the CR star lighting.)

The museum is the original depot station (which ended up in CR after a vote about where to put the county seat. CR won, so they got the courthouse and rail depot.)

The graffiti you see on the walls is original, the workers who worked on the rail would sign their name and date in charcoal on the rhyolite walls.

Yes, that date is 1875, the year the depot was finished. The rhyolite was quarried off a butte near the area, it makes good building material and it’s right there, so they used it.

The station is set up with a small replica of a general store of the time, some train equipment (Morse code telegraphing machine and flag pulling machine),

some artifacts from the Indians of the area (this gun was modified with caps which were only available from the government – this way they could keep a check on how much ammo the Indians had),

some CR history,

archaeological history and ranching history.

Here are two unique items that I have never seen before, the first is a milk bottle with a bulb shape used to hold the cream.

The cream would rise to the top and there is a spoon that rests between the small part of the neck of the bulb and the rest of the bottle, you could easily siphon off the cream this way. The other is this paper grocery list from the local grocery store, he used it as an advertisement (but really, where else are you going to get your groceries if you lived out here during that time?)

Figs get their own category as well as lamp supplies, lard, macaroni and bluing.

From http://www.visitcastlerock.org/history.htm: Castle Rock was named for the prominent rock formation that overlooks the Town, the discovery of rhyolite stone in the butte near Plum Creek is what put Castle Rock on the map and made it an important station for north-south railroad traffic.

One of the original homesteaders, Jeremiah Gould, owned 160 acres to the south of “The Rock.” At that time, the community consisted of just a few shacks for prospectors, quarry workers and other hired hands. In 1874, Gould donated 120 acres to “be known as Castle Rock.”

The museum is free and is located at 420 Elbert st. in Castle Rock. They are open Wed-Fri 12-5pm and Sat 12-4pm.
